- $\Delta G = \Delta H - T\Delta S$

Answer: can be negative, but numerically smaller than $\frac{x}{298} cal K^{-1}$

$\Delta G = \Delta H - T\Delta S$

For spontaneity, $\Delta G < 0$

As $\Delta H$ = - x kcal is negative and T = 298 K.

For $\Delta G$ to be < 0, $\Delta S$ can be negative but numerically less than $\frac{x}{298}cal K^{-1}$
